Installation
Homebrew (recommended)
winget (Windows)
Easiest way to install on Windows — one command, no PATH setup needed:
Quick Install (Linux/macOS)
> Installs to ~/.local/bin. Add to PATH if needed: >
Cargo
Pre-built Binaries
Download from releases: • macOS: rtk-x8664-apple-darwin.tar.gz / rtk-aarch64-apple-darwin.tar.gz • Linux: rtk-x8664-unknown-linux-musl.tar.gz / rtk-aarch64-unknown-linux-gnu.tar.gz • Windows: rtk-x8664-pc-windows-msvc.zip
> Windows users: Extract the zip and place rtk.exe somewhere in your PATH (e.g. C:\Users\ \.local\bin). Run RTK from Command Prompt, PowerShell, or Windows Terminal — do not double-click the .exe (it will flash and close). The full hook system works natively on Windows (and in WSL). See Windows setup below for details.
Verify Installation
> Name collision warning: Another project named "rtk" (Rust Type Kit) exists on crates.io. If rtk gain fails, you have the wrong package. Use cargo install --git above instead.
Quick Start
Hook-based agents rewrite Bash commands (e.g., git status -> rtk git status) before execution. Plugin-based agents, including Hermes, use their plugin API to rewrite commands before execution. The agent receives compact output without needing to call rtk explicitly.
Important: the hook only runs on Bash tool calls.…

No endorsements yetNo verified confirmations yet — be the first.
Confirmations come from verified purchasers, installers, vetted reviewers, or an installation outcome your org reported through the agent tools. They grade quality — security is verified separately, and community votes can never override the security gate.

04Trust Passport
Full passport →0/0 automated components pass. An automated score is never a security guarantee.
This listing is unclaimed, so publisher identity cannot be verified and it stays below the “verified” tier by design — that is a statement about the listing, not about the project’s quality. Our automated scans still ran; a maintainer who claims it unlocks identity verification.
